 nehmen, wie Fig. 5 zeigt, von ihrer Mitte gegen die AuflagerendeIl an Breite ab, während die
Träger o der Unterdecke von der Mitte gegen die Enden an Höhe abnehmen (Fig.   4).   



   Die Ausschalung der Decke erfolgt in nachstehender Weise : Nach genügender Erhärtung des Betons werden die Latten c von den Ständern a entfernt und die Formen q durch den zwischen den Pfosten tU und dem Rande der Platte   h   der Unterdecke herausgezogen. Nun werden durch
Entfernen der Stifte m die Streben   1   gelöst und die andere Teilform um die Gelenke k und n zusammengeklappt und in diesem Zustande herausgenommen, desgleichen die Bleche r.

   Ist der
Beton endlich soweit erhärtet, dass sich die Konstruktion selbst trägt, wird der restliche Teil der Gerüstung   abgenommen   und die zwischen den Platten   h   der Unterdecke vorhandenen offenen
Streifen durch Verbindung der Enden des Rabitznetzes und darauffolgende   Ausbetonierung   u geschlossen, wodurch die gesamte Deckenkonstruktion fertiggestellt erscheint. 



     Zweckmässig   werden, wie Fig. 5, rechte Seite, erkennen lässt, die Rippen p der Tragdecke in die Mauer fest eingelassen,    während   die Träger o der Unterdecke auf letzterer frei aufliegen. 



    PATENT-ANSPRÜCHE:     1.   Eisenbetondecke, dadurch gekennzeichnet, dass die Unterdecke von der Tragdecke vollständig getrennt ist, so dass Schwingungen der einen Decke auf die andere fast ohne Einfluss bleiben. wodurch die Schallsicherheit wesentlich   erhöht   wird.

 as FIG. 5 shows, decrease in width from their center towards the support end, while the
Remove the support o the suspended ceiling from the middle towards the ends in height (Fig. 4).



   The shuttering of the ceiling is carried out as follows: After the concrete has hardened sufficiently, the battens c are removed from the uprights a and the forms q are pulled out through the between the posts tU and the edge of the plate h of the suspended ceiling. Well be through
Removing the pins m the struts 1 released and the other part of the shape folded around the joints k and n and removed in this state, as well as the sheets r.

   Is the
Concrete has finally hardened to such an extent that the construction is self-supporting, the remaining part of the scaffolding is removed and the open parts between the panels h of the suspended ceiling
The strips were closed by connecting the ends of the Rabitz network and then pouring concrete into it, making the entire ceiling construction appear complete.



     As can be seen in FIG. 5, right-hand side, the ribs p of the supporting ceiling are expediently firmly embedded in the wall, while the carriers o of the lower ceiling lie freely on the latter.



    PATENT CLAIMS: 1. Reinforced concrete ceiling, characterized in that the lower ceiling is completely separated from the supporting ceiling so that vibrations of one ceiling have almost no influence on the other. whereby the sound safety is significantly increased.

Claims

2. A method for producing reinforced concrete ceilings according to claim 1, characterized in that the lower ceiling opposite the ribs (p) of the supporting ceiling initially remains interrupted, so that gaps are created between the edges of the parts of the lower ceiling and the scaffolding for the supporting ribs of the upper ceiling , through which the forms used for the formation of the cavity remaining between the supporting and suspended ceiling after their dismantling or Can be taken out when folded, after which after connecting the ends of the into the Rabitz net or a similar plaster base embedded in the ceiling, the interruptions in the ceiling are closed by re-concreting.

3. To carry out the method according to claim 2, a molded body for the formation of the cavity between the supporting ceiling and the lower ceiling, consisting of two molded parts articulated with one another (at k) which are held in an angular position in the position of use by a strut (1) and an approximately right-angled rigid form jacket (q), which rests on the one hand on the scaffolding and on the other hand on one leg of the collapsible part t

4. Reinforced concrete ceiling according to claim 1, characterized in that the supporting ceiling above the ribs (p) is reinforced by concreting (t). between which reinforcements the Upholstery wood for the floor are arranged sunk. EMI2.1
